. 2 Claims. (Cl. -194101) This invention relates to coin-controlled mechanism and is more particularly directed to a device for removing magnetic slugs from the coin chutes of such devices.

An object of the inventionis the provision of a coin-controlled mechanism in which a chute is provided. to receive the usual pieces of metal money for releasing certain elements of the coin-controlled mechanism to permit the dispensing of goods, a device being employed in connection with the chute for removing magnetic slugs when some party has attempted to operate the coin-controlled mechanism in an illegal manner.

A further object of the invention is the provision of a coin-controlled mechanismfor dispensing goods in which a chute is employed toreceive pieces of money with the chute having an opening at one side and a rotatable magnet adjacent the opening for Withdrawing slugs and discharging the same from the chute, thereby preventing unauthorized operation of the dispensing device.

This invention will be best understood from a consideration of the following detailed description, in view of the accompanying drawing form'- ing a part of the specification, nevertheless, it is to be understood that the invention is not confined to the disclosure, being susceptible of such changes and modifications which shall define no material departure from the salient features of the invention as expressed in the appended claims.

In the drawing:

Figure 1 is a view in elevation of the coincontrolled dispensing device partly in section showing the principles of the invention,

Figure 2 is a vertical section taken along the line 22 of Figure 1, and

the line 3-l-3 of Figure 1.

Referring more particularly to the drawing, 10 designates a housing provided with a coin slot 11 which provides an entrance to a coin chute generally designated by the numeral 12. This Figure 3 is a horizontal section taken along crank 21 for operating the shaft. A disc 22 is secured to the shaft and is directly rotated thereby. Asecond disc 23;, spaced from the disc 22, is loose on the shaft.

A pair of rods 24 and 25 are pivotally connected on a crankpin 26 secured to the disc 22 The lower end of the rod 24 is pivotally connected with-one arm of a bell-crank lever 27. The other arm of the bell crank lever is pivotally connected at 28 with a slide 29 movable within a slot 30 formed in one wall of a dispensing chamber 31. The bell crank lever 2'1 is pivotally mounted at 32 on a bracket 33 secured to one face of the dispensing chamber 31.

The rod 25 is pivotally connected at 34 with a lever,35 which in turn is pivoted at 36 on a. bracket BI eX tending from the other face of the dispensing chamber 31. A plate 38 is pivotally connected at '39 with the lever 35 and is movable through a slot 40 formed in the wall of the dispensing chamber 31.

The pin 36 is rigidly secured to the lever 35 and also to an arm 41 which extends downwardly along one side of the: dispensing chamber 31 andis provided with a lug42 adapted to'engage beneath. the free end of ahinged closure 43.

A bar 44 is pivotally. connected at" 45 with V the disc 23'and extends downwardly and passes through an opening 47 formed in a bracket 48. The passage. 47 acts as a guidefor the bar 44. A spring 49 secured betweenthebar 44' and the side wall of the dis'pensing. chamber 31 is adapted to pulb the ,bar 44 towards the adjacent side wall of the chamber31.

[The lower endof the bar 44 is provided with a cam member 50 having an inclined face. The upper end of the cam'member is provided with a slot 51 adapted to receive an arm 52 secured rigidly to a shaft 53. The closure 43 is rigidly connected to the shaft53 or to the arm 52, 'so that when the arm 52 is rocked, the 010- sure'will. likewise be rocked.

A plunger has a curved end 61 projecting into the portion 15 of the chute l3 and forms a seat to engage a coin, indicated in dotted lines and shown at 62. A rod 63 is pivotally mountedat64 with the plunger 60 and has its free end 64 adapted to engage a finger 65 which is formed integrally with a stop or lug 66. The finger 65 and lug 66 form, together a bell crank lever which is mounted at 6'? on the disc 23. A spring 68 has one end secured to a bar 69 and the other end is connected with the lug 66.

A link 70 is pivotally connected at '71 with the rod 63 while the other end ofthe link is piv- 'most position.

is suspended from the top of the housing. 10.. A

spring 79 tends .to maintain the plunger bar 76 in its uppermost position. The lower end' of this bar is provided with a curved .head.80..

which is adapted to engage the coin 62andforce it downwardly into the chute portions;..15,and';16. and thus move the plunger 60 outward-1y of the chute portion 15.

The bar 76 is provided with a lug 81 adapted to be engaged by a pawl 82 pivotallyi'mounted;

at 83 on the disc 22. A spring 84 maintains the pawl '82 in a predetermined position sothat it will be engaged by the lug 81 when said'lug moves to an-upwardposition, as-shown in Fi'g--- ure 1.

A pawl'85 has one-end, as-shown at 86, pivotally mounted on the disc 22. The other end,

as shown at 87, is adapted-to-engageteeth 88 of a ratchet wheel 89 which is mounted for H rotation and-is securedto a'shaft 90.

A magnet 91 has magnetic bars92 and 98' secured to its ends and these-barsareseparated by insulating material 94.- The magnet, as

shown in Fig. 2, is securedto-the shaft 90 so that when the ratchet wheel-=89 is revolvedthe 'magnet will berotated.

The portion-14' of the chute is providedwith a slot 95 adjacent the magnetic plates 92 -93 so that when a slug-formed of magnetic mate-- rial is dropped in through the-chute 13 it will be picked upby the magnet and held'until the magnet and the ratchet wheel 89gare-revolved as will be presently described for removing'the slug "fromthe chute; V

The operation'of our device is as follows: A loaf of bread or other article, shown at 100, is supported in the dispensing; chamber 31 by the closure 43whichis hldin place by the latch member 41 since" the latchmember and the closure plate 43 are'located within thehousing 10' it' will beimpossible foranyone to release the latch member 41-and open-the closure 43 to obtain articles in the dispensing chamber; The articles-190 are deposited within a drawer (not' shown) at the bottom 'of'the housing; A coinis" deposited in the slot 11" and" passes" downwardly through the chute and" rests uponthe' seat 61'of the-plunger A handle 21 is then operated in the'direction" indicated by the arrow in Fig. 1. Since the pawl'82'is in=engage ment with*the lug'81, said" pawl will'forcejtlie plungenbar 7'6 downwardly so that the plunger foot 80 will engage the coin 62 andforce it-past the inner'projecting endoftheplunger'60: As

the coin is forced' past the'inner end of the" plunger" 60 the plunger is moved outwardly, thereby exerting a pull "on the rod fiS, thus moving the rod-inthe direction'indicat'ed' by the ar row sothat thefree end 64 of the rod is-released from the finger The spring'68then" draws the lug 66" upwardlyso that a" pin 66*"on the lug will be engaged by-a lug or tooth 91 formed on the disc 22'. Continued rotation of the disc through the crank or handle 21 will cause the disc 22 to be moved, thereby moving the rods 24 and 25 in the directions indicated by the arrow so that the plates 29 and 38 will be moved inwardly of the slots and engage the bottom of the next article and retain. it in the uppermost position above the article 100 in the dispensing chamber 31. When the disc 23 is revolved the rod 44 is also moved upwardly in the direction indicated by the arrow so that the lever 52 will be rocked, moving the cover 43 downwardly-in the direction indicated by the arrow. However, a movement of the rods 24 and 25ibeingiin:.advance.of. the movement of the rod 44,.the lever 35 will be rocked when the plate 38 isshiftedinwardly and the latch 41 will be releasedbefore the rod 44 is operated to rock the closure 43.

At the time that the bar 63 is shifted the link '70 wil-l also be moved downwardly, thereby releasing thecoin, as shown at 102, which is then deposited with-in the till18.

If on the other hand; a magnetic slug is dropped into the slot ll-it will roll downward- 1y into the chute 13 untilit comes opposite the mag-net 91. This magnetfwill attract the slugto the same sothat when the ratchet wheel '89 is revolved-by the pawl 85, the coin willbe moved outwardly through the slot 95until it engages the top 1030f the chute portion 14, whence the slug-will be forced away from the magnet.

It will-be seenby this construction that when the proper coins are placed within the slot 11 the device may-be operated for dispensing bread or any other article. On the other hand when magnetic slugs-are placed in the device the magnet will remove them'when the handle operated.
